Lenovo BIOS for a board labelled IGLKMS, version 1.0, in a 5.62 MB ZIP archive. IGLKMS appears to be a Lenovo desktop board code, but the name states no model. The image is intended for programming the SPI flash with an external programmer to recover a machine with corrupted firmware. Read and back up the original chip contents before writing, check that the board marking matches IGLKMS, and make sure the dump size corresponds to the flash chip capacity.
